Gearboxes PM, PMC and PMK

are designed for direct drum drive of truck concrete mixer with drum working volume 6 – 16 m3. Drum of concrete mixer body is in application assembled to gearbox driving flange that transmits torque from fluid motor to concrete mixer drum. Gearbox serves concurrently for mounting of front part of drum. Gearboxes PM51 are delivered as alternative ones, with water pump drive (mark no.1)
and without water pump drive (mark no. 2), whereas in case of the alternative with water pump drive, two versions are possible: right & left. Various types of fluid motors produced may be used for drive. In case of square gearboxes PMK 60 a PML 60 two versions are possible
